BERGEN, Norway – Scantrol has delivered an active heave compensation (AHC) package for a launch and recovery system (LARS) to serve an observation ROV. The LARS is designed by Hydramec.
This is the first time that Scantrol has designed an AHC LARS system in collaboration with Hydramec. Now the two business partners are taking the technology one step further to meet the requirements from the subsea industry. For this client, Hydamec was tasked to develop a LARS design that had ease of operation and maintenance, as well as the ability to achieve the working parameters required to extend operational time for the ROV vessel. Hydramec chose Scantrol as its partner in building and supplying the control system for this LARS.
The LARS was designed around an OBS ROV LARS design already manufactured by Hydramec, with the hydraulic system altered to suit the applications required to achieve the AHC specifications, which was 5 m (16 ft) of active heave over a 10-second period at a depth of 1,200 m (3,937 ft).
Related to the delivery of the system, Hydramec and Scantrol were asked to assist with the installation of all the equipment onboard the vessel and to eventually carry out live tests during sea trials off the Singapore coast. Once all parameters were achieved, the vessel then sailed for Congo, where it is due to start operations in September.
