MMT has recently performed long baseline (LBL) positioning in a light construction project with Reach Subsea for ExxonMobile Russia Inc.

The LBL was used to establish the right position of the two Subsea Accumulator Modules (SAMs) and three acoustic baskets at Balder Site D. The sites were surveyed and inspected to locate the best possible sediment situation and the operations was performed from MMTs long term chartered vessel Stril Explorer. The two 20 ton SAM units were deployed with the heave compensated crane onboard and oriented with a mounted fiber optic gyro on the  top beside the LBL transponder. The ROV maneuvered the SAMs in to the right orientation and position.

The operation was very successful and the units will be tested on the well site during May and then recovered by Stril Explorer again in June. After the recovery the units will be transported and taken into production in the Kara sea.
