Vessel safety survey

Last updated

Vessel safety surveys are inspections of the structure and equipment of a vessel to assess the condition of the surveyed items and check that they comply with legal or classification society requirements for insurance and registration. They may occur at any time when there is reason to suspect that the condition has changed significantly since the previous survey, and the first survey is generally during construction (built under survey) or before first registration. The criteria for acceptance are defined by the licensing or registration authority for a variety of equipment vital to the safe operation of the vessel, such as safety equipment, lifting equipment, hull structure, static stability, ground tackle, propulsion machinery, auxiliary machinery, etc. The SOLAS Convention (International Convention for the Safety of Life at Sea), specifies safety equipment for commercial vessels operating internationally.[ citation needed ]

Classification societies, such as Lloyd's Register (LR), Bureau Veritas (BV), American Bureau of Shipping (ABS), Det Norske Veritas (DNV), and the Indian Register of Shipping, [1] publish standards for structure, stability and equipment,[ citation needed ] and maintenance to the standards is needed to secure vessel insurance and so that access to ports is not impeded by local port authorities. [2] These independent businesses likely belong to the International Association of Classification Societies. National authorities such as the US Department of Transport publish safety regulations for the ships registered under their flag. Surveys are also required by marine insurers, as the risk is assumed to be affected by the condition of the vessel. A ship that passes a classification society's survey for a given class of registration is said to be "in class".[ citation needed ]

A survey or partial survey is often made on a vessel for a potential purchaser, to ensure that the condition is as claimed by the owner. A purchase may be made subject to survey, in which case the extent of the survey may be specified by the purchaser and made by a surveyor nominated by the purchaser or by a marine surveyor from a classification society. A professional survey will include a written report on the items inspected and their condition as assessed by the surveyor.[ citation needed ]

Construction and equipment surveys

Ships must be surveyed by persons or organisations recognised for this purpose by the ship's flag state, and relevant certificates issued as evidence that the vessel has been designed, constructed, managed and maintained to comply with International Maritime Organization codes and conventions/ [3]

The relevant conventions include: SOLAS, 1974, MARPOL 73/78, Tonnage 69, Load Lines, COLREG 72, AFS 2001, BWM 2004 and others. [3]

The certificates and documents are subject to inspection by port state control officers. [3]

Structural surveys

The extent of the survey depends on the age and type of the vessel. Certificates issued by the classification societies are generally valid for five years. During these five years different controls on the hull are made (there are three damage levels, if the vessel of the damage levels check ups, it will not receive the certificate),[ clarification needed ] and on the engine. To keep a certificate all class requirements are compulsory. The continuous survey hull (CSH) and Continuous survey machinery (CSM) are survey methods for the mooring, anchoring and the propulsion system. The special survey cycle (SS) is an alternative for the CSH [ clarification needed ] and Engine survey (ES) for the CSM. The annual survey (AS) is an inspection of the safety equipment. The annual inspection can be done during a three months period before or the three months after the annual date. There should be two docking surveys (DS) during the five years of certificate validity but it is possible to substitute one by an in-water survey which includes a diving inspection. The intermediate survey (ITSS) is done between the second and the third year, and the scope of this survey depends on the age the vessel. Generally, it is an inspection of ballast more or less detailed.[ clarification needed ] For the chemical or oil carrier surveys are more intensive with the age.

In some circumstances survey of underwater structure and equipment can be done using divers. [4]

Safety surveys

All merchant cargo vessels must have certificates of compliance for: Ship safety construction, Ship safety equipment, Ship safety radio in to be legally permitted to navigate. Firefighting and life-saving safety exercises should be practiced regularly. The means of evacuation (life raft, life boat, or other marine evacuation system) must be launched once a month and maneuvered once every three months. The GMDSS (global maritime distress on safety system) are controlled by the certificates.[ clarification needed ] The pyrotechnic equipment is not tested on board, but the personal protective equipment such as immersion suits and life jackets are regularly tested during exercises for abandoning ship or at the master's discretion. The firefighting masks and breathing apparatus are tested weekly, but fire hoses are rarely tested inside the ship.[ citation needed ]

Hoist surveys

Lifting equipment is often used on a ship to load and unload heavy cargo or other goods. The controls are important. All the surveys are noted in the Register of Ship's Lifting Appliances and Cargo Handling Gear; the inspection is directed by the classification society.[ citation needed ]

Surveys in harbour

Port State control

All the vessels are not controlled when they arrive in harbor, it depends on many characteristics (age, flag state, cargo, quality of classification society ...). The Memorandum of understanding (MOU) is a group (area) to avoid this restrictive investigation. The control is determined by « target factor » described above. If the vessel have esthetic deficiencies, the reparation shall be made before the next inspection, but on the other hand the safety equipment must be in order, in case of excessive structural corrosion the vessel is put in detention and cannot navigate. The ship can be banned by the region of the MOU.[ clarification needed ][ citation needed ]

Cargo

Every cargo in ship is controlled before being unloaded. The controls are strict for the chemical and oil carriers and are conducted by an independent surveyor. The ullage is a means to calculate the quantity in the tanks; the sample of content gives an idea of the quality (density and temperature) of liquid in tanks. The surveyor must have records of the three last cargoes to know if there are problems of compatibility (IMDG code). On older vessels, inspections are made more frequently, especially for oil carriers, to avoid disasters such as the Erika as an example). For dry bulk cargo, it is compulsory to fumigate against rats.[ citation needed ]

Human survey

Competence of seamen

All merchant vessels are operated by a human crew, so the maintenance and upgrading of skills important. The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) created by IMO is a convention which made the rules for training. The STCW certificate is compulsory to navigate in merchant ship as a master and an officer. This certificate guarantees that the holder has the required basic knowledge and skills specified by the safety rules (fire fighting, medical, survival techniques, and management) and navigation (use of a chart etc.).[ citation needed ]

Management

The captain runs the vessel with the help of the officers and crew to ensure the safe operation of the vessel. The muster list gives the instruction during the accidents (fire, evacuation).[ clarification needed ] During the first twenty four hours of sailing there are compulsory exercises to familiarize the crew with the safety equipment and procedures on board a ship. One abandon ship drill and one fire drill per month are also required.[ citation needed ]

The classification societies made the rules to delivered certificates and some societies deliver more easily certificates because the owner of a ship has influence.[ clarification needed ] The IMO is trying to conduct all the surveys and the maintenance.[ clarification needed ] If the Classification societies are more restrictive the owner can change it.[ clarification needed ][ citation needed ] All seamen need a good and regular training to become a good seafarer.

The Port of Hong Kong, located by the South China Sea, is a deepwater seaport dominated by trade in containerised manufactured products, and to a lesser extent raw materials and passengers. A key factor in the economic development of Hong Kong, the natural shelter and deep waters of Victoria Harbour provide ideal conditions for berthing and the handling of all types of vessels. It is one of the busiest ports in the world, in the three categories of shipping movements, cargo handled and passengers carried. This makes Hong Kong a Large-Port Metropolis.

The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty that sets minimum safety standards in the construction, equipment and operation of merchant ships. The International Maritime Organization convention requires signatory flag states to ensure that ships flagged by them comply with at least these standards.

A second mate or second officer (2/O) is a licensed member of the deck department of a merchant ship holding a Second Mates Certificate of Competency, which is issued by the administration. The second mate is the third in command and a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the cargo operations.

<span class="mw-page-title-main">Third mate</span>

A third mate (3/M) or third officer is a licensed member of the deck department of a merchant ship. The third mate is a watchstander and customarily the ship's safety officer and fourth-in-command. The position is junior to a second mate. Other duties vary depending on the type of ship, its crewing, and other factors.

International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) sets minimum qualification standards for masters, officers and watch personnel on seagoing merchant ships and large yachts. STCW was adopted in 1978 by the International Maritime Organization (IMO) conference in London, and entered into force in 1984. The Convention was significantly amended in 1995 and 2010 entered into force on 1 January 2012.

<span class="mw-page-title-main">Deck department</span>

The deck department is an organisational team on board naval and merchant ships. The department and its manning requirements, including the responsibilities of each rank are regulated within the STCW Convention, applicable only to the merchant fleets of countries who have ratified it. The department is led by deck officers, who are licensed mariners, and they are commanded overall by the ship's captain. Seafarers in the deck department work a variety of jobs on a ship or vessel, but primarily they will carry out the navigation of a vessel from the bridge. However, they are usually also responsible for supervising and monitoring any maritime cargo onboard, as well as ensuring maintenance of the deck and upper hull structure, monitoring the stability of the ship, including loading and discharging ballast water, carrying out mooring operations, and finally anchoring a ship.

A Marine Surveyor is a person who inspects, surveys or examines marine vessels in order to assess damage, inspect or monitor their condition and that of any cargo onboard. Marine surveyors also inspect equipment intended for new or existing vessels to ensure compliance with various standards or specifications. Marine surveys typically include the structure, machinery and equipment and general condition of a vessel and/or cargo. They also involve judging materials on board and their condition. Because certifications and subsequent payments are processed only after the surveyor has expressed his or her satisfaction, a marine surveyor holds a prestigious position in the shipbuilding industry. Marine Surveyors are highly qualified and technically sound, and are usually selected after thorough evaluation procedures. Their duties apply to a wide range of seafaring vessels.

Seafaring is a tradition that encompasses a variety of professions and ranks. Each of these roles carries unique responsibilities that are integral to the successful operation of a seafaring vessel. A ship's crew can generally be divided into four main categories: the deck department, the engineering department, the steward's department, and other. The reasoning behind this is that a ship's bridge, filled with sophisticated navigational equipment, requires skills differing from those used on deck operations – such as berthing, cargo and/or military devices – which in turn requires skills different from those used in a ship's engine room and propulsion, and so on.

An oiler is a worker whose main job is to oil machinery. In previous eras there were oiler positions in various industries, including maritime work, railroading, steelmaking, and mining. Today most such positions have been eliminated through technological change; lubrication tends to require less human intervention, so that workers seldom have oiling as a principal duty. In the days of ubiquitous plain bearings, oiling was often a job description in and of itself.

Indian Register of Shipping (IRClass) is an internationally recognised, independent ship classification society, founded in India in 1975.
