Stemat Marine Services was a service company (within the VolkerWessels group) for maritime work, based in Rotterdam, Netherlands.
Business services are a recognisable subset of economic services, and share their characteristics. The essential difference is that businesses are concerned about the building of service systems in order to deliver value to their customers and to act in the roles of service provider and service consumer.
Royal VolkerWessels Stevin N.V. is a major European construction services business with Dutch-based headquarters. It is privately owned by the Wessels Family (42.5%), CVC Capital Partners (42.5%) and management (15%).
Maritime transport is the transport by water of people (passengers) or goods (cargo). Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air, despite fluctuating exchange rates and a fee placed on top of freighting charges for carrier companies known as the currency adjustment factor (CAF).
Stemat started with a few vessels in 1986, expanding to a fleet of more than 50 vessels. In the port in Rotterdam, Stemat had over 14,500m² of harbor space, 160m of wharf, frontage, and 13,500 m² of storage space. The wharf was equipped with mobile cranes with a hoisting capacity of up to 23 tons.
A harbor or harbour is a sheltered body of water where ships, boats, and barges can be docked. The term harbor is often used interchangeably with port, which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors.
A wharf, quay, staith or staithe is a structure on the shore of a harbor or on the bank of a river or canal where ships may dock to load and unload cargo or passengers. Such a structure includes one or more berths, and may also include piers, warehouses, or other facilities necessary for handling the ships. Wharfs are often considered to be a series of docks in which boats are stationed.
A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. They are designed to easily transport to a site and use with different types of load and cargo with little or no setup or assembly.
Stemat owned a wide variety of modern equipment, including multi-purpose vessels, crane barges, pontoons, pushers, and tug boats. [1]
Floats are airtight hollow structures, similar to pressure vessels, designed to provide buoyancy in water. Their principal applications are in watercraft hulls and aircraft floats, floating pier and pontoon bridge construction, and marine engineering applications such as salvage.
A pusher, pusher craft, pusher boat, pusher tug, or towboat, is a boat designed for pushing barges or car floats. In the United States, the industries that use these vessels refer to them as towboats. These vessels are characterized by a square bow, a shallow draft, and typically have knees, which are large plates mounted to the bow for pushing barges of various heights. These boats usually operate on rivers and inland waterways. Multiple barges lashed together, or a boat and any barges lashed to it, are referred to as a "tow" and can have dozens of barges. Many of these vessels, especially the long distances, or long haul boats, include living quarters for the crew.
In 2016, Stemat was acquired by Boskalis.
