Norwegian shipbuilder Simek has recently delivered the 'Stril Mariner' to Simon Møkster Rederi in Stavanger, Norway.
The 'Stril Mariner', named at a ceremony on October 30, 2009, measures 78.6 metres long with a 17.6-metre beam and a moulded depth to the main deck of 7.7 metres. With a 3,755 deadweight tonnage, the PSV has tankage for: 910 cubic metres of fuel oil, 925 cubic metres of fresh water, 1,250 cubic metres of drill water and 1,010 cubic metres each of mud, liquid mud and brine.
Additional tankage includes 175 cubic metres of methanol, 150 cubic metres of glycol, 315 cubic metres of dry cargo and 1,300 cubic metres for ORO. The cargo deck is 755 square metres.
Accommodation is provided for 31 people and there is also a deck office, a hospital and a conference room.
The vessel is certified by ISO 9001:2000 (Quality) and ISO 1401:2004 (Environmental).
Designed by the Havyard firm of naval architects, the 'Stril Mariner' has all tankage installed so that there is no storage of liquids that could harm the environment against the ship's hull shell.
In addition to this and other provision, the vessel gains its green designation as a result of the diesel electric propulsion system.
The vessel only uses the engines required to maintain the task at hand, thus, the resulting emissions, as well as fuel costs, can be dramatically reduced.
To achieve this flexibility in the main propulsion system, the 'Stril Mariner' is fitted with four Cummins KTA50-(D)M engines each of which turns a generator to produce up to 5,164kW of power.
This can drive the two azimuthing (Roll-Royce Marine, Ulstein Aquamaster, model US 205 CRP) drives for main propulsion as well as a pair of bow thrusters. Engines and generators can be shut down when holding position or travelling at reduced speed thus reducing the released pollutants.
The 'Stril Mariner' is classed by DNV with Class Notation * 1A1 Fire Fighter I OILREC SF LFL* COMF-V(3) E0 DYNPOS-AUTR NAUT-OSV(A)CLEAN DK(+) HL(2.8).
A sister ship to the 'Stril Mariner' is slated for delivery in the northern spring.
