The Vessels have been designed in close consultation with leading offshore, oil, and drilling companies in order to incorporate the latest developments in the industry. This provides for the safest, fastest and most reliable transports and installations within the semi-submersible market.
As the exclusive commercial management for
COSCOL, NMA represents their fleet of
semi-submersible self-propelled vessels which
include:

Purpose Built & State of the Art
Design based on extensive feedback from drilling operators,
fabrication yards, and engineering contractors.
Fast Ballasting System
44 independent ballast tanks are arranged in three levels for safety and
versatility. Ballasting operations are controlled by large capacity compressors
operating at 8,000 tons per hour, enabling ballasting operations
to be completed in just over two hours.
Fully Redundant Class 2 Dynamic Positioning System
The only fully redundant class 2 DP semi-submersible heavy lift ships.
High Design Speed of 15 Knots Fully Loaded
The propulsion system is based on a pair of Siemens Schottel twin
azimuthing pods. These 4.7 MW SSP units give the ships a design speed of 15 knots fully loaded and maneuverability is further enhanced by two 800 kW bow thrusters.
Fully Integrated Bridge System
All controls are centralized through a fully integrated system
located on the bridge.
Easily Removable Stern Bouyancy Casings
The vessels are fitted with two fully removable stern buoyancy casings, which can be placed horizontally or vertically. When not in use, these
casings can be stored under the forecastle for a completely unencumbered open deck.
High Internal Strength
The cargo deck has an overall strength of 18 t/m2 with single 705 ton High Internal Strength
point loads over centerline and side bulkheads and 682 tons over the
hull side shell. The vessels are capable of stern or side loading.
Optimized Hull Shape
Improved motion characteristics due to the vessel having hulls that
have been designed to slant inwards as opposed to the
conventional box-type shape. |
