Realization of two large-scale investment projects related to development of the transit transportation corridors using the Northern Sea Route started in Sakhalin Region.
Completion of the projects is scheduled for 2027.
In 2022 “Pacific Engineering Company” Ltd. performed the following engineering surveys at following facilities as a part of the investment projects implementation:
The following surveys were performed for reconstruction of the existing infrastructure facilities of Korsakov port and construction of new ones: berths №1, №2, №3 and №4, the seawall, operational water zone and approach channel of the Southern cargo district; operational water zone and approach channel of the “Fishing port”; systems of the navigation safety assurance; coal railway overpass; the road and access roads, the road bridge, coast protection, etc.
The field works included the following surveys: bathymetric survey, engineering-geological surveys (drilling of engineering-geological boreholes from jack-up “Krot”, sampling from SV “Diabaz”, drilling of engineering-geological boreholes from the ramp of URB-2D-3 on KAMAZ); engineering-geophysical surveys from “Yamaha” launch (MBES, SSS, SBP and magnetometer survey); engineering hydro meteorological investigations and micro seismic zoning. Laboratory testing of the soil samples were carried out and technical reports were prepared.
Onshore surveys and shallow-water offshore drilling works were conducted at the mentioned facility. Drilling of engineering-geological boreholes on the shore was performed using drilling unit URB-2A on the basis of TT-4 caterpillar tractor and small-size drilling rig “Korvet – 05”; MINI jack-up drilling rig was used for drilling of the engineering-geological boreholes in the shallow-water areas. Survey vessel “Diabaz” was involved in the works within the seaward part of the water area. The engineering-geological cross-section was studied to the depth of 40 m.
PECO football team participates in the Russian Mini-football Championship among unprofessional teams of the season 2019/2020 (II Championship League of Sakhalin Region) in the fourth division. The competitions started on November 4th, 2019 and they will last till April, 2020. By December 23rd, 2019 four games were played, two of them were won, one was lost and one – stand-off. The team is actively preparing for the tournament “Winter ball 2020” and “Night football league 2020”.
PECO Football club review
PECO unprofessional club was founded in January, 2017 under support of the General Director of “Pacific Engineering Company” Ltd. D.P. Cheremisin and Chairman of the Sakhalin Regional Football Federation A.Y. Abakumov.
For the period of the sport life the unprofessional football team took part in different municipal and regional competitions:
– “Night football league 2018 and 2019”,
– “Cup of Sakhalin Region for mini-football 2017, 2018 and 2019”,
– “Winter ball 2018 and 2019”,
– “Cup of Sakhalin Region for football 8 х 8”.
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.
Based on the information provided by the Director of ANO “Creative association of Sakhalin cinematographers” Alexander Zarchikov the second expedition using the divers-searchers within the sunken vessel location was performed on October 8-9, 2022. Sakhalin divers Yan Dyatlov, Vadim Legenkin and Evgeniy Vyatkin discovered the vessel at the depth of 37 m, examined it and carried out video recording.
In November, 2020 the investigation of the seabed in Aniva Bay was performed from survey vessel “Diabaz” near the Anastasiya Cape. As a result the sunken Japanese escort ship CD112 affected by the American torpedo during the last month of the Second World War was detected.
