On October 19th, 2018 PECO celebrated the 20th anniversary of its establishment (April 21, 1998). The book “Surveyors. In the sea and on the shore” devoted to the 20th jubilee was produced, it describes the investigating activity for previous 10 years and represents the continuation of the first book published in 2008 to the tenth anniversary of the company.
“Pacific Engineering Company” Ltd. has performed several large projects – both offshore ones on the shelf of Sakhalin Island and onshore surveys.
1. Offshore complex engineering surveys in the area of subsoil plot of federal significance including the field “Kaigansko-Vasyukanskoe-Sea”. The surveys were executed for construction of the exploratory well from the semi-submersible drilling rig (SSDR), for designing of the production complex and pipeline route from the site to the shore. Client – «Elvari Neftegas» LLC.
The following works were performed from survey vessel “Diabaz”: bathymetric survey by a multibeam echo sounder, hydroacoustic survey by a side-scan sonar, high resolution seismic, ultra-high resolution seismic, high-frequency and low-frequency continuous sub-bottom profiling, magnetometer survey and sampling; hydrometeorological and ecological investigations were performed. The following works were performed from survey vessel “Trias”: geotechnical drilling, СРТ, vertical seismic profiling (VSP) in the boreholes, field laboratory complex of the soil testing onboard the vessel. The works under the project “Kaigansko-Vasyukanskoe-Sea” will be continued in 2020 in accordance with the contract.
2. Offshore engineering geological and geotechnical surveys for development of the project documentation for the facility: “Sakhalin-1 Project” Arkutun-Dagi field. Central and Southern areas of Dagi structure. Construction of the underwater production facilities”. Client – “Exxon Neftegas Limited”.
The surveys were performed for positioning of the SEFDR (self-elevating floating drilling rig) for development of the areas of Central and Southern Dagi. Complex offshore engineering surveys were carried out for subsequent construction of the underwater production facilities including the patter wells, templates and flowlines. Survey vessel “Trias” was used under the project, the following works were performed from the vessel: drilling of engineering-geological boreholes, CPT, vertical seismic profiling in the boreholes. Complex of laboratory soil testing was carried out in the process of drilling works. The works have been completed in full.
3. Complex offshore and onshore engineering surveys for development of the project documentation for the facility «Sakhalin – 1 Project». Development Stage 2. Far-Eastern Liquefied Natural Gas (LNG) Production Complex. Offshore facilities. Onshore facilities». De-Kastri, Khabarovsk Territory. Client – Branch of the corporation “FLUOR DANIEL EURASIA INC.” (FLUOR), Technical Client – SNGT.
Jack-up drilling rig “Krot” and onshore geotechnical party were involved in the engineering-geological surveys. A new small-size tracked drilling unit “Korvet 05” was purchased for realization of the project. Five survey facilities have been completed under the contract, works at one of the facilities will be continued in 2020.
All laboratory tests under the projects have been performed in the stationary geotechnical laboratory. All works have been executed with strict observance of the safety requirements and environment protection.
Pacific Engineering Company Ltd. together with the Sakhalin cinematographers performed the expedition for searching of the sunken Japanese escort vessel CD112 torpedoed by the American submarine SS120 “Barb” in July, 1945. The search was conducted as part of the work on the historical documentary film “Secret of the Anastasiya Cape” of ANO “Creative association of Sakhalin cinematographers” (Director – Alexander Zarchikov). The survey was executed from the geophysical vessel “Diabaz”. Geophysicists of the company Oleg Novozhilov and Maxim Poznukhov explored the seabed by the side scan sonar, and Alexander Zarchikov coordinated the search. The works lasted more than 24 hours, vast area of Aniva Bay was scanned considering the surveys performed by the previous expeditions.
As a result, on November 22nd the sunken vessel was detected at the depth of 38 m at the Anastasiya Cape in Aniva Bay. The obtained sonograms fixed wreck of the war vessel 54 m long; the vessel bottom, deck-house and pipe are clearly seen. Large wrecks are observed all round, supposedly the stern destroyed as a result of torpedoing and detonation of the depth bombs.
On May 26th, 2021 the meeting of the Council of the investment activity was conducted. The ceremony of awarding of the small and medium business enterprises of Sakhalin Region achieved the highest operating rates in 2021 was held at the meeting.
Governor of Sakhalin Region V.I. Limarenko presented the commemorative to D.P. Cheremisin for the active participation in development of the business climate in the territory of Sakhalin Region.
