Sailors assigned to Underwater Construction Team (UCT) 2, Construction Dive Det. Alpha, completed a recompression chamber inspection and maritime infrastructure assessment of the Pohnpei Harbor and Kapingamarangi Atoll on May 7, as part of Pacific Partnership 2019.

The assessment, which began April 16, will help maintain and expand the harbor port in Pohnpei and improve navigation safety in both Pohnpei and Kapingamarangi Atoll, according to Petty Officer 2nd Class, Jasen Moreno Garcia.

“We came to Pohnpei for Pacific Partnership 2019 to inspect the faces of the wharf in the Pohnpei Harbor and do multiple hydrographic surveys, including surveying both the harbor in Pohnpei and Kapingamarangi Atoll,” said Construction Electrician 1st Class, Daniel Lehne, the project supervisor.

Lehne also mentioned that the channel in Kapingamarangi Atoll is currently not only very narrow, but also has a very difficult 90-degree turn. The hard turn and the narrowness prevent larger vessels from transiting during increased sea states.

“The surveys we completed will allow us to formulate a calculated plan using [precision placement of] explosives and other dredging techniques to widen the channel, making it a much safer passage for local ferries and the boats bringing supplies to the atoll,” said Lehne.

The UCT 2 team also performed a wharf inspection at Pohnpei Harbor using specialized equipment to test the current thickness of the metal wall in the wharf face. The measurements taken will be used as a baseline measurement for future inspections to help track the deterioration of the metal on the face over time.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
