The Milford Haven Waterway faces its busiest decade since the start of the oil boom in the 1950s.

Port Authority general manager, Ted Sangster, said: "We are looking forward to some wonderful activity on the haven."

Work should begin soon on the two LNG terminals at Waterston and South Hook, Milford Haven, which will bring increases in shipping during construction and once they are operational.

Consent is also being sought for two power stations - one by RWE npower on the former Pembroke Power Station site, the other at the Petroplus Waterston site.

Again materials and equipment could be brought in by sea.

Mr Sangster said he understood planning consent would soon be sought for the proposed £70 million marina development at Pembroke Dock.

The scheme, called Martello Quays would encompass a 500-berth marina, cruise ship berth, commercial and leisure facilities and 160 residential properties.

"I understand a planning application will be submitted in late spring or early summer," he explained.

Changes are also in the pipeline for the Royal Naval Dockyard, which is operated as part of the Ministry of Defence's Warship Support Agency.

"I understand the MOD is looking to franchise that part and it is going through a bidding process," said Mr Sangster. "We are always seeking new opportunities, and we would have an interest in extending our port facilities and could use part of the site to bring in commercial shipping."

There have also been 'various expressions of interest' in the former Mine Depot site at Blackbridge, Milford Haven.

"It is one of the few development sites left with access to the Milford Haven Waterway," said Mr Sangster.

"We will be working with the county council and we would encourage anyone looking at it, to make use of the site relative to the waterway, rather than housing."

A public exhibition unveiling RWE npower's plans for the former Pembroke Power Station site will be held on February 3rd, 4th and 5th at Pembroke Town Hall.
