April 2006 saw Remontowa S.A. signing the contract with Finnish Owners OY Gaiamare AB and Meriaura OY for the construction and delivery of two specialized cargo vessels, with delivery scheduled for 2007.
Each of the vessels is a multi-purpose cargo carrier intended for transport of ships’ steel blocks and sections, heavy equipment, containers or rocks, stones, logs and timber as deck cargo.
The vessel is a mono-hulled open deck carrier with forecastle and accommodation block with wheelhouse located fore.

Despite her compact design, the Atlantic Guardian carries the technical equipment to perform all maintenance and repair services: Double rotary cable machines, A-frames and special winches for ROV- and plough deployment as well as a centralised control and monitoring system. The special hull form, in combination with a dynamic positioning system and stabilizing tank, provide a stable and comfortable platform for cable repair operations in the North Atlantic.
The task and requirements
With more than 85% of the world’s telephone, fax and Internet traffic routed via sub sea cables, the ability to respond quickly to cable faults is crucial. The Atlantic Cable Maintenance Agreement, a consortium of several Cable Owners awards a multi-vessel contract to UK based Global Marine Systems. The C.S. Sovereign being the example for a fast but compact cable maintenance ship to cover the Western Atlantic region.

The intended main purpose of the vessel is the survey of measures being conducive to the maintenance of the fish population. The main operational area are the waters of EC states, mainly North Sea and Baltic Sea. Design and outfitting of the vessel allow world-wide operation.
Twin propulsion plant gives the vessel a maximum speed of 20 kts. The main diesel engines and / or the electric propulsion motors transmit their power via reduction gears to controllable pitch propellers.
Two high performance flap-type rudders and one 400 kW bow thruster guarantee vessel's excellent ma-noeuvring characteristics.
The seakeeping behaviour of the vessel can be influenced by means of a fin stabilization system. To carry out control missions at sea two fast and robust rescue/working boats are available. With jet drive respectively twinscrews the boat will have a speed of more than 30 kts.
The "SEEADLER" is the most sophisticated and best equipped vessel of the units operated by the Federal Office for agriculture and nourishment.

Dutch know-how in the field of heavy-load transportation is encapsulated in this versatile breed of vessels. The 4-vessel programme was entrusted to Merwede by Mammoet Shipping (Big lift at the time) of Amsterdam. The two mast cranes, each of 400 tons with 18 m radius, provide a tandem lift capacity of 800 tons and symbolise the primary purpose of these vessels; the stability of the vessels is such that no external measure like pontoons, outriggers or supports are required during heavy lift operations. The vessels are extremely flexible with a large single hold in which vertical transverse and longitudinal separations as well as tweendecks can easily be fitted by means of special pontoons making the vessels also suitable for bulk cargoes, timber, containers, dangerous goods and general cargoes apart from heavy lift and project cargoes.

The vessel is designed as a full scantling vessel with tween-deck, single screw propulsion and a deckhouse located aft. Main task of the vessel is the transport of project- and heavy lift cargo.
In addition the vessel is equipped for transport of standard containers. 40 plugs for reefer containers are available. The tween-deck hatch covers can be positioned at three different levels and are designed for a distributed load of 3,5 t /m². Two cranes with a150 t SWL each are arranged on port side. In coupled operation modules with a single weight up to 300 t can be handled.
Heel compensation for an efficient cargo handling required during loading operation will be ensured by an automatic anti-heeling-plant with a pump capacity of 500 m³/h.
Additional support to increase stability during loading operations can be reached by a stability pontoon. The pontoon can be fixed alternatively at port or starboard side and allows flexible use. For excellent manoeuvrability the vessel is equipped with a high power flap-rudder and a bow thruster.
The Crew is accommodated in single rooms with private bath cabins, officers have in addition a separate bed room.

MSV Botnica represents the same concept in a slightly smaller scale than its elder sisters. It also introduces a new feature - a moon pool, which allows many offshore operations, such as operating a ROV, to be carried out in heavier weather conditions than with conventional methods.

The vessel is especially designed and constructed to meet the requirements for standby support work, ice breaking, and barge towage in the shallow waters in the North Caspian Sea.
