Maritime Developments (MDL) has launched an innovative portable vertical lay system for the deployment and retrieval for subsea umbilicals, risers and flowlines.
The company, which has operations in Aberdeen and Peterhead, highlighted the sys5tem at its stand at Offshore Europe last week.
A market leader in the delivery of pipelay systems and associated equipment, MDL’s VLS system has several advantages over similar systems currently on the market.
The MDL system is road transportable; can be assembled on the quayside; can be used with any vessel of opportunity and requires only two lifts onto the vessel, one for the VLS, and the other for the tensioner.
This latter benefit allows for smaller, more readily available cranes to be used. Additionally, the innovation is lighter than other systems currently available.
The integrated VLS includes a work platform/moon pool doors; hang-off clamp; a control cabin; tensioner; top chute and HPU (hydraulic power unit)/spares container.
MDL’s innovation has unique runway beams for straightforward and safer introduction of buoyancy modules to the product. The VLS system is compatible with MDL’s patent-pending 4-track tensioner systems.
Derek Smith, chief executive officer at MDL, said: “We’ve had an extremely positive response from the market place. Our in-house designed and built VLS system gives clients greater control in this important arena of subsea projects.
“We have the full suite of back-deck equipment and the expertise to deliver projects not only in the North Sea but worldwide. Additionally, beyond its weight benefits, the fact our system is transportable via road is appealing.”
In addition to securing key projects in the North Sea for international contractors, MDL has expanded in the past year into markets such as the Gulf of Mexico, Asia/Australia and West Africa.
