UK tanker and marine services group James Fisher is expanding again with takeover deals worth £13.1m ($16.7m).

It has agreed to buy 100% of Martek Holdings in the UK and 60% of Saudi firm Murjan Al-Sharq for Marine Contracting (MSMC).

Martek is costing £9m, with another £1m potentially due depending on profit targets for the year ending 28 February 2020.

It was founded in Rotherham in 2000 and provides marine safety and calibration systems and products.

Unaudited profit after tax for the 12 months ended 28 February last year was £1.8m. Gross assets were £7.2m.

Fisher is paying £4.1m for MSMC, with another £4.5m possible, subject to profit targets for this year.

MSMC, which was established in 2010 by Abdullah Akbar Natheer and is headquartered in Al Khobar, provides near-shore marine construction and maintenance services.

Natheer will retain 40% and work with Fisher to grow MSMC.
