DML Supports Tauranga Boys College in Fiji

Tauranga Boys College recently returned from Fiji where they undertook a post cyclone rebuild of the Yamacia Rugby Clubs' youth accommodation block. In one week the team of students, teachers and locals built a new accommodation block for the team with the aid of generous donations from local and New Zealand companies. DML spends a lot of time working throughout the Pacific and considers it our "back yard". We are pleased to have been able to give back in a small way by supporting Tauranga ...

DML Staff & friends take on the 2016 Tawharanui Coastal Challenge

The 23km Mid-Monty distance event was held through the Tawharanui Regoinal Park, Auckland and required 'Team DML Loaded' to run, walk, hobble, scramble, wade, climb and crawl their way around some of Auckland's most pristine coast. The course took us east from Campbells Beach through numerous bays across white sand, stones, gravel, boulders and gnarly rocks. Next we were up and over the peninsula through a mixture of native bush trails and grassed tracks which offered awesome panoramic views ...

Surveying Bridges & Super-Structures

Surveying Bridges & Super-Structures Bridges and other structures spanning waterways present challenges when it comes to asset management and maintenance. The structure lifespans are typically measured in decades, with both the surface and subsurface components subject to a number of stresses and strains over long periods of time. Bridges are often subject to tidal flows 24 hours per day. Understanding the extent and nature of any scouring around the main bridge piles, can be key to he...

Ōpōtiki Harbour Development – a clear mandate to develop economic & social wealth

It was pleasing to be present at today's Applicant briefing for the investigation, design and construction of the Ōpōtiki Harbour Development project. Robert Edwards, Chairman of Whakatōhea, is clearly a passionate supporter of the Harbour Development given the benefits it will bring to the community. The estimated R.O.I to the community, by way of new business development and employment was expressed numerically; an impressive ratio in itself. However what is really exciting, is the downs...

Need to inspect submerged infrastructure?

We've been working with mobile laser scanners and our multibeam echo sounders to produce 3D data and images where we combine the data sets from both below and above the waterline. This is an ideal way of inspecting and monitoring submerged infrastructure. Our Senior Surveyor, Declan Stubbing undertook a trial last year to prove this application and achieved some exciting results. Feel free to contact Declan direct to discuss whether this may be of interest in your business. declan@dmlsurveys...

Investment in training is considered mandatory at DML

Keeping people up-to-date with the latest technology and best practice is a constant challenge for any organisation given the expense and necessary time-out of day to day operations. However, DML considers this as mandatory for business sustainability. The operation and knowledge of high end swathe sonars for engineering, port maintenance/development and national charting agencies is a complex business. DML is ensuring its people are staying abreast of advances in sonar capabilities and i...

Coda Echoscope

DML recently had a visit from Coda Octopus, demonstrating their impressive 3D real time imaging sonar, the Echoscope. The echoscope sonar has an 128x128 beam acoustic array which provides over 16,000 data points per return at over 10hz. This means the user can see a real time 3D imaging video in zero visibility subsurface conditions. DML sees the potential for this tool to supplement traditional multibeam bathymetry surveys in hard to access areas such as under large wharfs and structures, a...

The Next Generation

Getting the next generation into hydrography and marine science is close to the hearts of the team at DML. More often than not these disciplines fly under the radar. The House of Science (http://www.houseofscience.org.nz/) at Waikato University's Sulphur Point Marine Lab is supporting local teachers with pragmatic applied science kits for their classrooms, to help stimulate interest in the sciences. Recently DML assisted the House of Science by sponsoring the development of a new resource kit....

Laser Scanning from a Vessel

We recently conducted a trial in Auckland, New Zealand whereby a Terrestrial Laser Scanner was mounted to the roof of our vessel PANDORA II and driven around Westhaven Marina and the Auckland Harbour Bridge. The trial will form the basis of a paper being presented at the Australasian Coasts and Ports 2015 Conference in Auckland in September. The locations for the trial were scanned at a rate of 2000 points per second, the detail of which is not evident in these images. The results exceeded our...

New Images of the HMNZS Waikato and Rainbow Warrior Wrecks

High resolution hydrographic surveys for nautical charting of two of New Zealand's prominent recreational game fishing harbours have been completed by DML. Whangaroa and Tutukaka Harbours are well known to the New Zealand and international game fishing fraternity as well as many recreational anglers.The recent hydrographic surveys provided highly detailed images of the sea floor. While on location DML took the opportunity to survey the wrecks of HMNZS Waikato and the Rainbow Warrior. Images sh...

PANDORA II, DML’s new dedicated MBES survey vessel.

The demand for Multibeam Echo Sounder (MBES) surveys is increasing in New Zealand. DML has responded to the demand by recently commissioning a dedicated MBES survey boat. Pandora II is a 7.5m catamaran and incorporates a clever mechanism whereby the sonar transducer is raised and lowered through a moon pool arrangement located between the hulls and operated by a hand winch. Being a catamaran design, the boat is very stable and manoeuvrable and can operate in very shallow water. She is fitted w...

Challenges when working in 35 degrees plus

Working in the Pacific and Indian Oceans anywhere near the equator presents its own challenges. The heat and humidity play havoc with personnel and equipment. Seeking shelter or protecting yourself from the sun while conducting small boat and foreshore topographic surveys is essential if you are working long hours. The local flora and fauna can prove provide their own challenges. These large Palm Spiders in the Seychelles are 15cm across and while not poisonous do give the unwary visitor a nas...

Small vertical errors continued

Avoiding or minimising errors in surveys is related to the selection of; survey methodology, type of survey equipment and systems used in combination with the professionalism, skill and experience of the surveyors involved. The cost of "avoiding" the error varies from project to project and is a matter of using the right people and equipment for the area being surveyed. On average you could allow between 6-10% of the unnecessary disposal costs associated with the1cm dredging error. Vertical dep...

Small vertical errors in dredging volume calculations can have a sizeable impact on costs.

A 1cm error over one square km = 10,000 cubic metres. Dredging costs vary depending on method and disposal, but for arguments sake, let's say the cost per cubic metre is between $15 and $30. The 1cm error could result in an unnecessary cost of between $150K and $300K. DML provides an independent check on depths and volumes. Peace-of-mind & real savings to your bottom line. ...
