Mussalo and Hamina harbours expanded

New D section to the west of Mussalo Harbour will speed path of UPM pulp to the world

When UPM began to dream of a new pulp terminal in Kymenlaakso, Port of HaminaKotka Ltd took up the idea. A 20-hectare expansion was completed on the west side of Mussalo Harbour.

Terramare was closely involved in the expansion of the first phase of the new D section. Terramare’s contract included the construction of a new 261 metres long quay and a 620 metres long breakwater. In addition, Terramare professionals deepened the area’s extensive harbour basin.

Project Manager Jani Vyyryläinen explains that the contract was launched in summer 2018 with dredging work and underwater drilling and blasting. Around 670,000 m3 of material was dredged, mainly moraine.

“A total of 250,000 m3 of bedrock was removed from the site.”

Impressive breakwater

The blasted rock  obtained from the underwater drilling and blasting was used to make a breakwater, the construction of which started alongside the dredging.

Vyyryläinen describes the breakwater as unusually massive in Finnish conditions:

“The breakwater was covered with five-tonne stone cladding, which extends over an area of 25,000 m2. At some points the breakwater reaches a height of nearly 30 metres.”

The contract was completed in October 2019.

The massive upgrade of the port will improve the competitiveness of the industry at a national level: through the successful project, UPM will be able to concentrate very efficiently the sea traffic of the Kaukas and Kymi pulp mills via Mussalo Harbour.

“It will be much easier to get the pulp out into the world,” says Vyyryläinen.

Earlier double quay delivery to Hamina

Terramare is already a partner familiar to Port of HaminaKotka Ltd. In 2016-2018, Terramare implemented two quay projects for the company: the PK3 reception quay and river vessel jetty contracts, led by Project Manager Marko Saarelma. This was a major contract for the port to receive, stack and transport large modules to Kazakhstan. 

First, the reinforcement and extension to 140 metres of the Palokangas PK3 reception quay was carried out, in a contract that was completed in October 2017. The new river vessel quay, work on which began in May of the same year, measured 123 metres, including a mooring dolphin, and it was completed in April 2018.

The contracts included dredging, onshore and offshore piling, concrete and surface work, and installation of quay accessories.
